DESCRIPTION:Over the past 20 years\, the perception of groundwater resource
 s in the Northern Apennines has shifted significantly. Once considered a r
 egion of "poor hydrogeology" compared to the Alps and Central-Southern Ape
 nnines\, now some of their main aquifer units are recognized as a high-qua
 lity\, climate-resilient strategic resource. This renewed interest has bee
 n driven by scientific research along with the support from public water c
 ompanies (Gruppo Hera\, Montagna 2000) and direct hydrogeological observat
 ions from railway and highway tunnel excavations\, providing new insights 
 into groundwater flow systems active within the main fractured aquifers: s
 hallow marine Miocenic arenites\, foredeep silico-clastic or calcareous Pa
 leogenic and Neogenic turbidites and Jurassic ophiolites (peridotites and 
 basalts). This communication presents a synthesis of quantitative aquifer 
 parametrization\, covering both intrinsic properties (hydraulic transmissi
 vity and conductivity\, specific yield\, spring recession behaviour\, effe
 ctive groundwater velocity and kinematic porosity derived from tracer test
 s) and climate-related parameters including direct recharge and discharge 
 per unit area. It’s relevant\, for example\, the higher value of specifi
 c discharge (per unit outcropping area of the aquifer) of Pantano calcaren
 itic formation\, in the range 5-7 L/s on km2\, around twice respect to tur
 biditic deposits\, in the range 2-4 L/s on km2. These parameters serve as 
 critical inputs for hydrological modeling to determine sustainable withdra
 wal rates during droughts. Furthermore\, the findings and associated conce
 ptual models will contribute to the development of new guidelines for quan
 titative hydrogeological mapping\, coordinated and financed by ISPRA and a
 pplied to “Hydrogeological Sheet n°218 Castelnovo ne’Monti” which i
 s being carried out under the scientific supervision of the Hydrogeology g
 roup at the University of Bologna in collaboration with the Geological Sur
 vey of Emilia-Romagna region.
